Abstract: Methods used for life prediction of titanium matrix composites under isothermal and thermomechanical (TMF) fatigue are reviewed. Models containing a single parameter are shown to have applicability ...

Abstract: The analysis of the split Hopkinson bar experiment for determining dynamic material behavior is examined for several specific examples of specimen materials which exhibit strain-rate-dependent ...

Abstract: Fretting fatigue damage can reduce the service life of engineering components in contact. The attachment between blades and disks in the fan and compressor stages of gas turbine engines is ...

Abstract: Frequency effects on fatigue crack growth rates are examined in aluminum alloy 8009 in sheet and extruded product forms. The investigations show that frequency effects on the fatigue crack ...

Abstract: Observations of isothermal fatigue, isothermal fatigue with superimposed load hold times, and thermomechanical fatigue (TMF) crack growth rate behavior of Ti-24Al-11Nb are presented and compared ...

Abstract: Crack growth under sustained load and sustained load with superimposed fatigue cycles at elevated temperatures in a titanium-aluminide alloy (Ti3 Al) was investigated. The objectives were to ...

Abstract: Sustained-load crack-growth experiments were conducted under isothermal and nonisothermal conditions. Temperature cycling was conducted between 537° and 649°C. Hold times at minimum and/or ...
